How do wild and aquaculture fish differ at climate-associated alleles?
- 220k SNPs
- 5,267 Fish

How do wild and aquaculture fish differ at SNPs associated with climate?
Determining differneces in SNPs associated with climate
- RDA (redundancy analysis)
- Compare SNPs at RDA outliers
- Compare RDA outliers to FST outliers
- Gene Ontology Enrichment Analysis
Climate-Associated SNPs
How much overlap?
Are genomes more divergent at climate-associated SNPs?
River-Specific Climate-Associated FST
